technology was introduced in 2003, and the output of PQF tubes is expected to reach 4 million tons by the end of 2008. SMS Meer continuously enhances PQF technology with hydraulically adjusted three-roll arrangement. The latest plant generation that will be installed at Anhui Tianda, for example, has a maintenance- friendly, modular design that allows standstill times to be shortened, and productivity to be increased. The wall thickness tolerance of the finished tube is also improved. SMS Meer GmbH – Germany Fax : +49 2161 350 1667 Loeser GmbH is a major producer of premium quality belt grinding, polishing, brushing and deburring machinery for all types of materials. New grinding technologies enables quick combination of rough stock removal, tolerance and fine finishing with quick-change abrasive belts. It also enables major time advantages compared to stone grinding or turning. The company’s machines can be equipped with a number of stations in different combinations – open or closed and fully modular – that are easy to upgrade with additional stations. This patented technology is called pressure controlled grinding and is ideal for high production combined with low costs in belt consumption. Loeser claims that is far in advance of conventional grinding methods. A high number of stainless steel comp- anies have installed Loeser’s automatic centreless grinding and polishing RPS Email : info@sms-meer.com Website : www.sms-meer.de Top-class grinding and deburring technology

Premium solution for inner grooving copper tube MRB Schumag, UK, has achieved success with a number of contracts for inner grooving lines from commercial inner grooved tube producers across the United States and the Middle East. The inner grooving lines combine a revolutionary high-speed spindle motor with proven Veegroove Wheel drawing technology. The lines not only ensure a high-speed tube grooving unit, but also the fast and safe drawing of the tube through it. Lubrication systems with flow and pressure monitoring, tailored to suit the high speeds of the grooving process, safeguard the smooth passage of quality tube through the line. MRB Schumag’s premium solution affords line operators the opportunity to take a sample of their inner grooved tube, whilst the line is running at full speed, meaning quality control does not come at the expense of productivity.

The company has also focused on production efficiency, with customer feedback suggesting that its patented Reciprocating Die technology is significantly increasing the life of inner- grooving tooling. To further alleviate the increasing cost of tube production, two of the inner grooving lines can be operated simultaneously, back-to-back by just one operator.
